Answer:
Total money they had at first $252.
Step-by-step explanation:
Let,
x be the amount Silas had originally
y be the amount Raja had originally
According to given statement;
x = 3y Eqn 1
x - 84 = y + 42 Eqn 2
Putting x=3y in Eqn 2
3y - 84 = y + 42
3y - y = 42 + 84
2y = 126
Dividing both sides by 2
Putting y = 63 in Eqn 1
x = 3(63)
x = 189
Total money they originally had = 189 + 63 = $252
Hence,
Total money they had at first $252.
The correct answer is B- The surface area of B is greater than the surface area of A. I got this answer because...
Figure A's Volume= 60
Figure B's Volume= 60
Figure A's Surface Area= 104
Figure B's Surface Area= 248
So because the volumes are the same I knew it was not C or D, and then I solved the Surface Area for figures a and b and knew the correct answer is B.
Hope that helps. :)
